hi,
ok, i got my dell 600 and set up gentoo (what else  ) .. i'm using vanilla 2.4.21 and the latest acpi patch with a modified dsdt. readout of all acpi related values works, but setting the cpufreq seems not to work.. (btw: throttling works)
| Code: |
# cat /proc/acpi/processor/CPU0/performance
state count: 7
active state: P1
states:
P0: 1600 MHz, 32000 mW, 250 uS
*P1: 1600 MHz, 32000 mW, 250 uS
P2: 1400 MHz, 28000 mW, 250 uS
P3: 1200 MHz, 24000 mW, 250 uS
P4: 1000 MHz, 20000 mW, 250 uS
P5: 800 MHz, 16000 mW, 250 uS
P6: 600 MHz, 12000 mW, 250 uS
# echo 2 > /proc/acpi/processor/CPU0/performance
# cat /proc/acpi/processor/CPU0/performance
state count: 7
active state: P1
states:
P0: 1600 MHz, 32000 mW, 250 uS
*P1: 1600 MHz, 32000 mW, 250 uS
P2: 1400 MHz, 28000 mW, 250 uS
P3: 1200 MHz, 24000 mW, 250 uS
P4: 1000 MHz, 20000 mW, 250 uS
P5: 800 MHz, 16000 mW, 250 uS
P6: 600 MHz, 12000 mW, 250 uS

SpeedStep is enabled in BIOS.

I am trying 2.5.73 on my X31, the laptop only boot when config_acpi_ht_only is selected ( it disabled some other acpi options ).
when linux booted, in /proc/cpuinfo
only one cpu found, and the flags do not contain "ht" (for hyper threading). whY?? 
is there some trick to enable kernel support HT and recognize the Pentium-M ??
thx alot!

@Bloody Bastard
i tried the patch, but:
| Code: |
cpufreq: Intel(R) SpeedStep(TM) support $Revision: 1.7.2.6 $
cpufreq: Intel(R) SpeedStep(TM) for this processor not (yet) available.
|
so.. centrino speedstep != speedstep

So it is a centrino? I've heard of it being not supported yet
Try to google for it

To felicita;
The Pentium M is a development based on the mobile PIII. It doesn't support hyperthreading, only the PIV (I believe the northwood core) does

mb,
Did you ever get this problem figured out? I'm going through the same thing right now. |

i use the latest ac-sources (2.4.22-pre6-ac1 or something like this) and there you have the possibility to choose "Intel Pentium-M Enhanced SpeedStep" at the kernel config. i think that's it but i'm not sure. you can also choose normal intel speedstep and pentium 4 clock modulation.

@gangloot
well, not with 2.4.x (vanilla + acpi patch).. then i tried 2.6.0-test1 recently and it worked out of the box....
#mb
btw:
now i use this to switch between max power and max save..
| Code: |
echo -n "0:100:100:performance" > /proc/cpufreq
echo -n "0:0:0:powersave" > /proc/cpufreq
|
but both interfaces (/proc/cpufreq and /proac/acpi/processor/../performance) seems to be out-dated |
